3. Answer the following.
xvii. How are XeO3 and XeOF4 prepared ?
Answer:-
Xenon trioxide (XeO3) and xenon oxytetrafluoride (XeOF4) can be prepared through specific chemical reactions involving xenon compounds. Here’s how each of these xenon oxides can be prepared:
Preparation of Xenon Trioxide (XeO3):
Xenon trioxide (XeO3) can be prepared by the reaction of xenon hexafluoride (XeF6) with water (H2O). This reaction results in the formation of xenon trioxide along with hydrogen fluoride (HF) as a byproduct:
Reaction: XeF6(g) + 3H2O(l) → XeO3(s) + 6HF(g)
Xenon hexafluoride reacts with water to yield xenon trioxide as a solid precipitate and gaseous hydrogen fluoride. The xenon trioxide can be obtained as a solid product after the reaction is complete.
Preparation of Xenon Oxytetrafluoride (XeOF4):
Xenon oxytetrafluoride (XeOF4) can be synthesized through a reaction involving xenon hexafluoride (XeF6) and oxygen difluoride (OF2). The reaction proceeds as follows:
Reaction: XeF6(g) + OF2(g) → XeOF4(s)
In this reaction, xenon hexafluoride reacts with oxygen difluoride to form xenon oxytetrafluoride as a solid product.
Both of these reactions require careful handling and control of reactants, as the compounds involved can be reactive and must be carried out in controlled environments by experienced chemists. Xenon oxides are relatively rare and less commonly encountered in comparison to other xenon compounds.
